We compared 87 portographic filling defects detected by portal CT in 64 patients were compared with those obtained by indirect portography. The indirect portography could visualize portogram only in anterior-posterior view. But the portal portal CT could visualize both portogram and hepatogram. We examined the portal CT and indirect portography and compared the accuracy of the both methods to evaluate the limitation and significance of the indirect protography. The mass shape lesions were seen on the portal CT which means portal flow defects of the mass lesions only could not depict totally in indirect portography (0%, 0/41). And the larger defects than real mass lesion were seen in portal CT means mass with associated portal flow defect and find portal vein invasion around the mass in 52% (24/46) of the indirect portography. Among them, only 66% of mass were detected correctly in the indirect portography comparing with mass lesion in portal CT. In summary, indirect portogram could not detect small filling defects which detected in portal CT and could not depict the extent of large filling defects. It also could not visualize correctly the protal flow in non-lesion side of the liver parenchyma.

[Objective] The aim of this study was to investigate the effects of Joksamni (ST 36) combination on NADPH-diaphorase, neuronal nitric oxide synthase (nNOS), neuropeptide Y (NPY) and vasoactive intestinal peptide (VIP) in the cerebral cortex of spontaneously hypertensive rat.
[Methods] The experimental groups were divided into four groups : Normal, Joksamni (ST 36), Joksamni (ST 36) + Eumneungcheon (SP 9), and Joksamni (ST 36) + Gokji (LI 11). Needles were inserted into acupoints at the depth of 0.5 cm with basic insertion method. Electroacupuncture was done under the condition of 2 HZ electrical biphasic pulses with continuous rectangular wave lasting for 0.2 ms until the muscles produced visible contractions. Such stimulation was applied continuously for 10 minutes, 1 time every 2 days for 10 sessions of treatments. Thereafter we evaluated changes in NADPH-d positive neurons histochemically and changes in nNOS, NPY and VIP positive neurons immunohistochemically.
[Results] The optical densities of NADPH-d positive neurons of the Joksamni (ST 36) + Eumneungcheon (SP 9) group in all areas of cerebral cortex and Joksamni (ST 36) + Gokji (LI 11) group in primary somatosensory cortex, visual cortex, auditory cortex, perirhinal cortex were significantly increased as compared to the Joksamni (ST 36) group.
The optical densities of NADPH-d positive neurons of the Joksamni (ST 36) + Gokji (LI 11) group were sig-nificantly decreased as compared to the Joksamni (ST 36) + Eumneungcheon (SP 9) group with the exception of primary somatosensory cortex.
The optical densities of nNOS positive neurons of the Joksamni (ST 36) + Eumneungcheon (SP 9) group in all areas of cerebral cortex and Joksamni (ST 36) + Gokji (LI 11) group in auditory cortex, perirhinal cortex, insular cortex were significantly increased as compared to the Joksamni (ST 36) group. The optical densities of nNOS positive neurons of the Joksamni (ST 36) + Gokji (LI 11) group were significantly decreased in all areas of cerebral cortex as compared to the Joksamni (ST 36) + Eumneungcheon (SP 9) group.
The optical densities of NPY positive neurons of the Joksamni (ST 36) + Gokji (LI 11) group were signifi-cantly decreased in primary motor cortex, primary somatosensory cortex, cingulate cortex as compared to the Joksamni (ST 36) and Joksamni (ST 36) + Eumneungcheon (SP 9) groups.
The optical densities of VIP positive neurons of the Joksamni (ST 36) + Eumneungcheon (SP 9) group were significantly increased in all areas of cerebral cortex except f or cingulate cortex as compared to the Joksamni (ST 36) group. The optical densities of VIP positive neurons of the Joksamni (ST 36) + Gokji (LI 11) group were significantly decreased in auditory cortex, cingulate cortex, perirhinal cortex as compared to the Joksamni (ST 36) + Gokji (LIII) group were significantly decreased in all areas of cerebral cortex as compared to the Joksamni (ST 36) + Eumneungcheon (SP 9) group.
[Conclusions] The result demonstrated that electroacupuncture on Joksamni (ST 36) and its combination change the activities of the NO system and peptidergic system in the cerebral cortex of SHR and that acupoint combination is one of the important parameters for the effects.

Cardiac myxoma is the most common primary tumor of the heart. The tumor contains a variety of cell types that are thought to arise from a focus of primitive pluripotential mesenchymal cells in the area of the fossa ovalis. Throughout the myxoid stroma, there are variable amounts of reticular fivers, collagen, elastic fibers and smooth muscle cells. A 38-year-old female had right atrial myxoma with multiple pulmonary infarcts. In this case, we experienced an unusual degenerative change in the tumor of granulomatous lesion consisting of hemosiderin pigments, foreign body giant cells and peculiar, spheroid, semilunar or bamboo-shaped degenerated elastic fibers. Microscopically it resembles Gamna-Gandy nodule seen in the spleen of chronic passive congestion.

Authors performed angio-CT(portal &/or arterial CT) in 35 patients with various hepatic masses. We obtained portal CT in 32 and arterial CT in 13 patients. The contrast material was injected into superior mesenteric artery for portal CT and into hepatic artery for arterial CT after transfemoral cathetrization of these arteries. We concluded that portal CT was superior to other imaging modalities highly sensitive in detecting hepatic masses, especially, early hepatocellular carcinomas, daughter nodules, and subclinical metastatic hepatic malignancy, With this method, detection rate of early hepatocelluar carcinomas improved 62% in number of patients and 90% in number of masses. Detection rate of subclinical hepatic metastases improve 60% each in number of patients and in number of masses. It was also useful for the detection of portal vein invasion. Arterial CT was useful in differential of masses and in defining the characteristics of entire or part of the masses because this method revealed hemodynamic patterns more definitely.

Wide resection is an acceptable alternative to amputation for the management of primary sarcomas of the long bones or pelvis. The resected bone can be debrided of gross tumor tissue, autoclaved, and than replaced to reconstruct the limb anatomically. The procedure can be combined with prosthetic reconstruction of adjacent joints with sufficient strength to allow early unprotected weight-bearing. We had an experience of a large segmental defect in the shaft of the humerus after wide resection due to.a low grade malignant chondrosarcoma without extension to the surrounding soft tissues and this case had been managed by reimplantation after autoclaving the locally resected segment and autogenous iliac bone graft with a sound union and the favorable functional outcomes. So we are reporting this case with bibliographic reviews as a possible method of reconstruction for the management of the segmental defect which was produced by a local resection for a low grade malignancy.
